<font size="+1"><tt>Hi All,<br>
I thought somebody will find this useful and hence<br>
sharing it here.<br>
<br>
We are using opennebula based setup to test our<br>
collaboration product. We have home grown test framework<br>
which can run clients on different machines to execute<br>
test scenarios. Things were fine until we had only few<br>
users in our test. However as I added more users in test,<br>
the VMs deploying started taking too long because of the<br>
image copying. My frontend is on FC8, with big SATA disk. <br>
The datastore is expored using CIFS. The VMWare Hypervisors<br>
mount the datastore using CIFS to run the VMs.<br>
<br>
To minimize the copy of the whole disk on deploy, we<br>
followed solution detailed in 1, which is briefly mentioned <br>
as below.<br>
<br>
- Create your base image, call it basevm.<br>
- Modify the disk settings to non-persistent.<br>
- Now create another VM, clone1 , using the disk of <br>
basevm.<br>
- Set the new disk as non-persistent.<br>
- Create the vm template pointing to clone1. Note that<br>
both the basevm and clone1 images should be in your<br>
exported datastore path.<br>
- Deploy as many VMs as you like, with just few MBs of<br>
data to copied.<br>
<br>
Hope this helps somebody.<br>
